While some calcifications may indicate breast cancer, such as ductal carcinoma in situ (DCIS), most are noncancerous (benign) conditions. Benign causes of breast calcifications include:

  1. Previous injury or surgery to the breast (fat necrosis)
  2. Skin (dermal) or blood vessel (vascular) calcification
  3. Breast cysts — fluid-filled sacs in your breast that are usually benign
  4. Fibroadenoma — a solid, benign mass most common in young women
  5. Cell secretions or debris
  6. Mammary duct ectasia
  7. Mastitis — an infection in breast tissue that most commonly affects women who are breast-feeding
  8. Previous radiation therapy for cancer

Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
